MacOS X creates a hidden file, '.FBCIndex' in each directory that has been 
viewed with the Finder. This file contains the content of the files present 
in the directory, giving an attacker information on the HTML tags, JavaScript, 
passwords, or any other sensitive word used inside those files. 

Solution: Use a <FilesMatch> directive in httpd.conf to restrict access to 
'hidden' files:

<FilesMatch '^\.'>
Order allow, deny
Deny from all
</FilesMatch>

And restart Apache.
